    rienced physicians. To avoid all error it will be sufficient to remark, that the pulsations are limited in a transverse direction; that the impulse, instead of being gradual,is sudden ; that the murmur when it exists is very short, and is perceived along the whole course of the vessel, instead of being cir- cumscribed to one point; and finally, that the pa- tient manifests all the signs of an anemic condition, and of great nervous irritability. Progress, duration, terminations, and progno- sis. — The progress of the aneurism is commonly very slow. For.a long time, the tumour is COn- cealed, nor does the patient himself perceive it. It is only when it has acquired a certain size, and especially when it has caused cardiac disturbance, that dangerous general symptoms are seen to super- vene. Asa general proposition, we may say that its progress is subordinate to the resistance of the parts surrounding the aneurism. The duration of this disease is generally long, and depends on its form, the situation of the tumour, and the kind of life of the patient. Itis not rare to see patients live fora number of years with an aneurism of the aorta, and especially with aneurism from dilatation. Its du- ration may, however, be short. Aneurisms, for ex- ample, which arise immediately above the left ven- tricle, deprived as they are of cellular membrane, burst very soon into the pericardium. The aortic aneurisms ordinarily terminate by rupture at the end of a shorter or longertime. In some fortunate and very rare cases, the spontaneous cure of these diseases is observed. The rupture takes place by means of an eschar, or by a rent, according to the nature of the tissue which is perforated. The skin
